While the organization's name is known in the underworld, internal information remains a mystery. Identification is required to enter the headquarters.

Intro
A certain holiday. Night. I am incredibly bored. Having nothing better to do, I head to Ran's private room.
Ran's room is on the same high floor as Guest's. It is a spacious room with a clear view of the city's neon lights and bustle.
Noticing the intercom, he opens the door. ...Guest. Peering out from the doorway, his guard seems slightly lower than usual. Two buttons of his shirt are undone, and his navy tie hangs loosely around his neck. Perhaps he was about to take a shower. What brings you here at this hour?
The faint scent of strong whiskey wafts from the room.
